A brief history of the Bloomberg terminal
Tracing the evolution of the Bloomberg Terminal from its 1981 hardware roots to its modern status as a ubiquitous, high-priced financial workstation.
summary is enough The article provides an entertaining historical overview, while the comment thread delivers compelling technical insights into the platform's modern architecture.
summary
Michael Bloomberg launched Innovative Market Systems in 1981, building a dedicated financial workstation that combined real-time bond data with quantitative analysis for Wall Street traders. Backed initially by Merrill Lynch, the company expanded through proprietary hardware like custom keyboards and private networks before transitioning to software on standard PCs. Today, the annual subscription remains a defining status symbol and operational hub for elite financial markets. Commenters add rich technical context regarding its massive JavaScript codebase, Chromium base, and internal OCaml usage.
key points
- Innovative Market Systems secured a foundational $30 million investment from Merrill Lynch in 1982 in exchange for a 30 percent stake and temporary exclusivity.
- The physical terminal evolved from custom monochrome CRTs and hand-assembled Chiclet keyboards with finance-specific hot keys into a modern Chromium-based application.
- Commenters highlight hidden technical details of the modern platform, including a massive JavaScript frontend and an OCaml-based domain-specific language for pricing exotic derivatives.

discussion positive
consensus
Commenters express deep nostalgia and high praise for the terminal's legendary information density and ergonomics, frequently comparing its layout to avionics cockpits.
pushback
Some critics argue that the $32,000 annual price tag represents an unfair structural advantage that locks out smaller, independent developers and traders.
The modern Terminal is based on a private fork of Chromium to give it the look and feel of a VT100 terminal, and integrate their private networking and security technologies. The BBT predates HTTP, and backwards compatibility is hugely important to the company- they have a museum where a second-generation Terminal from ~1985 shows the current news, because they are so dedicated to backwards compatibility that they still can support the 1985 hardware.
Reveals specific internal architecture details, noting that the modern terminal runs on a private fork of Chromium styled after a VT100.
